Last week I attended a webinar about display advertising on a new private rtb network. I didn't sign up for the $ 1495 membership, but the main thing I took from the webby was that they are able to drop the retargeting pixel directly from the ad creative itself without having to send the visitor through a landing page. Meaning the pixel is generated per impression, not per click which makes a huge difference for the audience being built. Has anyone heard about this? What are your thoughts?
